Toilet heights vary depending on user height, preferences, and the design of your bathroom. From the standard 15-inch high, 17-19 inch chair height to above-20-inch toilets, there is a whole range of toilet heights around the globe.

The highest toilet measures 21 inches tall, floor to bowl rim height. With some proper adjustments, some wall-hung toilets can go up to a height of 28 inches. While some manufacturers offer custom-made toilets of above 19 inches, you can also extend your seat to any height of your choice.

To help individuals with sitting or standing difficulties, that is the elderly, handicapped and even extra tall people, the height of toilets has been increasing in the past few years.

A height of 17-19 inches is the standard high measurement recommended by  ADA (Americans with Disabilities Act). Although ADA compliant toilets are not as high as some individuals would expect, you can still consider them high, especially when compared to standard-height toilets which have a height that is not over 17 inches.

Toilet Height Measurement

The toilet features different dimensions, including the height from the floor (exterior height), seat height, toilet width, and bowl fittings, among other details. If you want to know how you can measure these dimensions properly, follow the steps below.


To start off, collect all the necessary equipment you need to measure. That includes,

  • Paper or notebook to write down the measurements.
  • A pen to write with.
  • Measuring tape or a rule.


Next up, jot down on a piece of paper the areas you would like to measure. Here are some measures you can take;

  • Toilet height – this is from the floor of the room up to the seat top of the toilet. Standard toilets will measure 14 to 16 inches and comfort toilets measure 17 to 19 inches.
  • Toilet seat height – this adds the toilet height from above to the extra inches measured from the toilet seat. It could be anything from one to four inches.
  • Bowl length – the bowl of the toilet can also be in two kinds; round and elongated. The round toilets measure approximately 24 inches with the elongated taking up an additional three inches in the front.
  • Toilet width – here you’ll only measure the widest section of the bowl or the tank if it’s a one-piece toilet. This measure is widely encouraged if you’re dealing with limited space or you’re building toilet stalls in a commercial area. A standard loo will have a width of 20 to 30 inches.
  • Rough-in measurements  – this defines the space between the wall / back of the toilet to the center of the waste pipe. For the standard toilets, they measure between 10 to 14 inches with a high probability of 12 inches.

ADA compliant wash sets are taller with a height of 17 to 19 inches, but the standard toilets are equally deeper measuring 27 to 30 inches and having a width of 20 inches. However, these ADA toilets compensate by having additional spacing in the toilet for rails, arms, and grab bars.

What/Who are Extra-tall Toilets Meant for?

We all have our own preferences, but with the tall toilets, their main aim is to aid users to avoid the process of squatting and getting up from the toilet seat. Now, obviously, this means that these users are either experiencing pains in certain areas like the knee, hip or back, or they’re disabled or they’re just tall in height.

Fortunately, here’s where the highest toilets come in. They come in to aid and assist such individuals to maintain stability, safety, and independence as they go about their business. Let’s have a deeper look into this from four perspectives;

  • Tall adults
  • Elderly/Seniors
  • Disabled
  • Handicapped

1. High Toilets for Tall People

The tall toilets are meant to offer a 90-degree knee posture so the user isn’t exerting too much effort. Unfortunately, for taller people, the regular-height toilets aren’t quite level for them. These toilets are considerably low hence, uncomfortable.

So how tall is a tall adult?

If you are 6’0″ (183 cm) or taller, you are considered a tall person. The 17 to 19 inches ADA compliant toilets are the most available but they don’t provide much comfort for extra tall people.

Standard toilets are best suited for those with a height of five feet and eight inches to about five feet and ten inches tall.

2. The Elderly/Seniors

The elderly suffer from many bodily ailments. From knee pains, aggravated joints, weak hips, and soar backs, among other issues. Hence, they are the perfect candidates for tall toilets.

The raised height by about two to three inches high makes a huge difference in that the user won’t need to go a long distance either getting up or seating down.

What’s more, the wash set can have an elongated bowl to offer more surface area for the user – therefore, more comfort. These toilets are also recommended for senior citizens since not only do they’re compensated in terms of height, but they also offer high performance and effective flushing systems.

3. The Disabled

As mandated by the ADA guidelines, the minimum height for a disabled toilet is 17 to 19 inches – from the floor to the toilet seat. The supposed height is said to emulate any given chair height, making it easier for the user to get on and off the toilet, regardless of how they get on it.

More commonly, you’ll find disabled people using wheelchairs,  this means that they move laterally from the wheelchair’s seat onto the toilet seat. With a tall toilet, it’s very easy for them to slide either way since the heights are similar. However, you can choose to get an even higher toilet to adequately cater to the disabled person.

4. The Handicapped

Last, but not least, the handicapped. They similarly follow the ADA guidelines, but they offer an allowance to even children whose height can be as low as 12 inches. As for the handicapped, their accessible comfort toilets mostly cater to tall users who would prefer an increase in the height of the toilet.

Plus, their tall toilets are also designed with 48-inch floor space, automatic flush control system, and a fixed and easy to reach toilet paper holder

What is the Average Height Toilet?

Regular height toilets are the same as standard toilets. They have a height of 14 to 16 inches – this is the height from the floor to the top of the bowl excluding the height from the toilet seat. They are suitable for small children and shorter adults. They could also be used by tall individuals, only when they are experiencing bowel movement problems. With the hips below the knee, one is naturally in a squatting position.

What is the Lowest Toilet Height?

You have read about the highest toilets, the standard height toilets, now let’s have a look at the lowest height wash sets. These ones are also guided by the ADA guidelines. What most people know is that the sets have to be 17 to 19 inches high with enough floor space, but that’s not the case for all.

The ADA recommended toilet seat height ranges differently for adults and children. From primary school-going children to children’s group homes, and other residential areas, the seats have to be low to cater to their height. Have a look at the table below.

UserAgeToilet Height (inches)
AdultAbove 18 years17 to 19
ChildThree to four years11 to 12
ChildFive to eight years12 to 15
ChildNine to 15 years15 to 18

As you can see from the table above, the lowest toilet measures 11 to 12 inches high to cater to children below the age of five years. They look the same as a commode or a potty since the children have a height of approximately two feet tall.
